Once a sufficient number of hood locking components have been collected, this activity will end. Dealers will be notified 30 days in advance of when Nissan intends to end this collection activity to enable dealers to communicate with their customers as necessary and complete previously scheduled appointments. ***** What Dealers Should Do**** 1.
